We have them here and they’re NOT the scrawny little things you see out west.
DNA tests suggest that they are wolf hybrids.
They are big, bold and do not fear humans.
A pack of them backed my dad down a ridge above my house.
Luckily, he was able to walk backwards [as they followed him] down to his truck where he retrieved his rifle.

After putting up with annual spring newborn livestock slaughters, the farmers started killing them.
We have less than we did but now have mountain lions headed this way.
[the DNR boldly denies their presence here *but* posts warnings everywhere about it being a felony to kill them plus a $10,000 fine. These fliers also list a 24/7 “Mountain Lion” hotline for sightings]
Useful with canines but absolutely critical if dealing with a mountain lion. They like to close from behind and people have kept them away by staring at them. In one case, the person turned their head away and the mountain lion moved a lot closer by they turned their head back to look at it again.
